Temblor Trouble

No deaths have been reported after a magnitude 6.5 earthquake struck thirty three miles off the coast of northern California. “A magnitude 6.5 earthquake rocked the Northern California city of Eureka on Saturday, snapping power lines, toppling chimneys, knocking down traffic signals, shattering windows and prompting the evacuation of at least one apartment building. There were no reports of major injuries, but the temblor, which struck at 4:27 p.m. about 33 miles southwest of the coastal city of 26,000, was powerful enough to send people running into the streets, some fearing a tsunami. Centered offshore about 13 miles deep, the quake was felt as far north as central Oregon, as far south as Santa Cruz and as far east as Reno, the U.S. Geological Survey said. ‘It was a monstrous one,’ said Phil Burns, owner of Mity Nice Bakery Cafe Restaurant in Eureka, which is about 80 miles south of the Oregon border. ‘Usually, they're sharp, but this one was very wiggly. It was rolling in all directions.’”
